ENERGY STAR places San Mateo County in its South-Central zone for window certification.
Normal temperatures run 50°F in January and 69°F in July, so the glass package worth paying for in Belmont isn't the same one that pencils out two zones over.

7 top-rated window replacement companies in and near Belmont
Ranked by Google rating weighted against how many people left one, so a perfect score from a handful of reviewers never outranks a strong average built on hundreds. That ranking is not a license check; call the state directly and ask for the contractor's license or registration number.
